微信服务商分账功能 PHP
项目说明
- 微信服务商分账接口说明：https://pay.weixin.qq.com/wiki/doc/api/allocation_sl.php?chapter=24_1&index=1
项目大概逻辑
- 开通分账功能（https://pay.weixin.qq.com/wiki/doc/api/allocation_sl.php?chapter=24_2&index=2）
- 服务商代子商户发起添加分账接收方请求
- 在统一下单API、付款码支付API、委托扣款API中上传新增参数profit_sharing，请求支付
- 支付完成后，调用请求分账接口，完成分账
其他注意事项
- 分账接口分为单次分账和多次分账
- 当用户需要退款时，单次分账调用接口的步骤是：分账回退->申请退款
- 当用户需要退款时，多次分账调用接口的步骤是：分账完结->分账回退->申请退款
- 这里画重点，商户系统内部的分账单号，在商户系统内部唯一（***单次分账、多次分账、完结分账应使用不同的商户分账单号），同一分账单号多次请求等同一次。**只能是数字、大小写字母_-|@
- Ilog是一个日志类，这里就不提供了，大家都有自己的
- ProfitSharingSign.class.php是用来生成签名的，跟微信支付、微信退款生成签名类是一样的，会贴在最后
- ProfitSharingCurl.class.php是一个发送http请求的类，会贴在最后
- pdo_*的方法是微擎框架自带的数据库操作（这框架估计没谁会喜欢…）
- 使用例子就不写了，单身狗都知道，new一个对象嘛，大家给我介绍一个也行的，然后照着参数传就行
- 最后，欢迎指错~~
